Pedro147:
you can use some C++ syntax in the Arduino environment, but anything that requires the use of C++ libraries will not work.
What are you talking about? The Arduino IDE uses C++. There is nothing about "some" C++ syntax.
... anything that requires the use of C++ libraries will not work ...
No. Some libraries are implemented. Next you'll be saying that strcpy doesn't work. A library is a library. If it is present you can use it. For example, you can use the STL library if you install it.
